Determine fouling margins in tubular heat exchanger design

Fouling, which is caused mainly by the deposition and accumulation of an undesired layer of solids on a heat transfer surface, is very common in tubular heat exchangers.

Improve refinery flexibility and responsiveness

Olsen, T., Schodowski, E., Emerson Process Management

The hydrocarbon processing industry (HPI) has changed significantly with an abundance of available discounted crude oils, a rise in markets served beyond the traditional local or regional demands, and a renewed focus on being both competitive and profitable while complying with ever-changing regulations.

Alfa Laval to supply heat exchangers for ethylene project in Turkmenistan

The Alfa Laval OLMI heat exchangers will be used to increase the yield and recover energy in the production of ethylene at the Turkmenistan project, according to company officials.

How Cr compounds discolor refractory brick walls of an ethylene cracking furnace

Al-Meshari, A., Saudi Basic Industries Corp.; Maity, M., Al-Zahrani, E., SABIC Technology Centre

Unusual pink coloration was noticed on the entire refractory brick wall in the radiant section of an ethylene cracking furnace of a petrochemical plant. The problem was investigated by evaluating the ..

How caustic stress leads to failures of incinerator caustic spray nozzles

Maity, M., Al-Zahrani, E., Al-Meshari, A., SABIC Technology Centre

Frequent failures of the waste spray nozzles in incinerators result in accelerated degradation of the refractory lining, requiring unscheduled shutdowns for repairs. A study was carried out to identify the factors that contributed to the nozzle failure and to prevent the reoccurrence of similar failures in the future.

Extend heat exchanger lifecycle with hyper-duplex stainless steel

Perea, E., Sandvik Materials Technology

Intensifying performance demands in refineries, coupled with the ongoing decline in crude oil quality, require a new and improved duplex SS grade to withstand increasingly tough operating conditions. This need has led to the development of hyper-duplex stainless steels.
